Summary

The AMM 10 multi-media connection system is a flexible, modular mixing system with a wide range of input and output modules. The individual modules are connected by a normal network cable (CAT 5) and can be fitted in standard mounting frames. Thanks to the plug-in design of the terminals, fitting the modules is very easy and requires little prior knowledge.

The modules can be fitted inside deep flush-mounted boxes or device boxes, cable ducts, floor boxes, etc., and can be combined with the cover frames of virtually every type of European switch.

Thanks to the flexible design, you can insert the required modules in the places where they are used. The system is designed to allow you to bridge long distances. This means that the input modules and the "master module" can be as far as 100 metres apart. Distances of up to 100 metres are also possible between the master module and the output modules.

Thanks to the flexible, modular system, the output signal can be tapped wherever you like. The maximum number of modules is limited only by the capacity of the power supply unit. Up to 10 modules can be connected with the supplied power supply unit PSU 10. Higher powered supply units are available on request.

Modules

MASTER CONTROL

The control and master output module is the heart of the system.

It receives incoming audio signals from all the input modules and, after amplification and tone adjustment, passes them to all the output modules.

This module must be connected to the system power supply (e.g. PSU 10).

D-MIC IN

The Mic/Line input module is a universal preamplifier module for connection of dynamic microphones or balanced line sources.

C-MIC IN

The C-Mic input module is a preamplifier module for connection of dynamic microphones and phantom-powered microphones.

The preamplifier is equipped with a limiter and configurable compressor.

CD/PCIN

The AUX / LINE IN module is a preamplifier module suitable for the connection of common, stationary AUX sound sources such as a CD player, tuner, cassette deck, etc., and also for portable audio devices such as MP3 players, Apple® iPod® and the like.

MP3/PC IN

The MP3 / USB POWER module is a preamplifier module suitable for connection of off-the-shelf MP3 players, Apple® iPod® or other portable audio devices via a jack socket. Battery power can be supplied to the connected device via a standard-compliant USB socket.

XLR OUT ACT.

The stereo line output module is an output module with electrically balanced stereo XLR output. It is used to connect e.g. power amplifiers, mixing desks and the like.

CONTROL

The headphone output module is an output module that displays the system output level with integrated headphone output.

REC OUT

The REC output module is an output driver module suitable for the connection of common, stationary recording equipment such as a CD recorder, cassette deck, etc., and also for portable recording equipment such as MP3 recorders, tape machines, etc.

XLR OUT PAS.

The stereo line output module is an output module with stereo XLR output (Line Out). It is used to connect e.g. power amplifiers, mixing desks and the like.

TRAFO IN

The TRAFO IN plug-in module can only be used in conjunction with the CD / PC IN module. The unbalanced inputs are kept potential-free by the isolating transformers.

TRAFO OUT

The TRAFO OUT plug-in module can only be used in conjunction with the AUX / LINE OUT module or the XLR OUT PAS. module. The outputs are kept potential-free and earth loops are effectively broken by the isolating transformers. Asymmetries and transient currents are also effectively prevented in this way.

PSU 10

Power is supplied by the PSU 10 power supply unit. Other power supply units not approved by us are not to be used!

3 Installation and Connection

Fitting the modules

RISK OF INJURY!

The devices must only be installed by authorised technicians.

Observe the following basic requirements prior to installation:

• Install the modules only in dry rooms.
• For installation use deep mounting boxes with an internal depth of at least 55mm .
• Clean any dust and other impurities from the mounting frames and mounting boxes. If necessary use a damp, but not wet, cloth.

The following criteria must be satisfied during installation:

• When installing, avoid proximity to parts under mains voltage.
• Use only shielded CAT5 cable.

It is permitted to use a CAT 5 cable with a conductor cross-section of not less than 0.12 mm² (AWG26) and not more than 0.5 mm² (AWG20).

• The PSU 10 power supply unit must be mounted directly adjacent to the control and master output module, as the operating voltage is supplied here.
• The optional REC OUT module must be installed one slot away from the control and master output module.
• Make sure that the shield and the drain wire do not touch any electronic components.

Assembly sequence

The assembly sequence is always the same, whether it is in a cavity wall box, a flush or surface-mounted box, a cable duct or a desktop case.

Make sure that the CAT5 cable has been correctly laid as far as the installation location.

Figure 1: Description of individual parts

1 = Mounting box 4 = Intermediate frame
2 = Mounting frame 5 = Module (schematic)
3 = Cover frame

1) Screw the mounting frame onto the mounting box.

Figure 2: Fastening the mounting frame

2) Place the cover frame and intermediate frame over the mounting frame and pass the CAT5 cable through these frames.

Figure 3: Fitting the cover frame and intermediate frame
Figure 4: All frames assembled

3) Connect the module as described under Connecting the modules (Page 40).
4) Align the module and screw it tight.

RISK OF DAMAGE!

Guide the module carefully and precisely into the mounting box. Make sure that the metal drain wire does not touch any electronic components and that none of the wires gets trapped or their insulation damaged.

Figure 5: Fastening a module

Connecting the modules

Preparing the cabling

Once you have fitted all the necessary mounting boxes and laid the CAT5 cable, you can start installing the modules.

RISK OF INJURY!

The PSU 10 power supply unit must be connected last.

This module may only be installed by qualified technicians, observing relevant technical regulations and VDE directives.

Connection of the protective earth (PE) conductor is obligatory.

Remember that the PSU 10 power supply unit and the optional REC OUT module have to be next to each other due to the length of the connecting cable.

CABLE LENGTH

Before cutting the CAT5 cable, remember to leave enough length in reserve.

Installing in cable ducts:

The cable should project by approx. 20~cm from the cable duct so that the module can be connected easily. A certain amount of cable can be left in reserve in case you want to move the frames in the cable ducts later on.

Flush mounting:

Insert the modules without applying much force. When choosing the cable length make sure there is enough space in the box for the installed module.

RISK OF DAMAGE!

Too much spare cable in the flush-mounted box can damage the cable or the circuit board. Pressing the circuit board against a cable may damage or even cut through it. Shorten the cable if necessary.

Stripping the CAT cable

1) Score the CAT cable about 5cm from the end and remove the sheath. Take care that you do not cut into or through the individual wires.

Figure 6: De-sheathing the CAT cable

2) Remove the shielding. Take a side cutter and cut into the shielding. The shield can now be removed so that the four wire pairs and the drain wire become visible.

Figure 7: Removing the shielding

NOTE

REMOVING THE SHIELDING

Ease a side cutter carefully under the shielding and cut into it a little. After that it can be loosened easily.

NOTE

EARTH POTENTIAL

Be very careful that you do not cut the metal drain wire of the CAT cable as this is needed for earth potential!

Wiring the modules

To avoid confusion, sort the wires into the correct colour sequence. All modules, if attached to the "bus", are always connected in the same sequence:

Figure 8: Wire connection scheme

1 = White-green

2 = Green

3 = White-orange

4 = Blue

5 = White-blue

6 = Orange

7 = White-brown

8 = Brown

9 = Drain wire

Connecting the modules

1) Strip approx. 6 mm of insulation from the individual wires. Use a suitable tool for this purpose (e.g. stripping pliers)

Figure 9: Conductors in correct sequence

2) Arrange the wires in the correct sequence; see connection scheme above.
3) Insert the wires one after the other in the terminal. Push the wires into the terminal until you feel a slight resistance. Using flat-nose pliers will make this easier. Make sure the stripped portion of the wire is not too long and does not project from the terminal. Shorten the core if necessary.

Figure 10: Connecting the wires

4) Fasten the CAT cable to the adjacent retainer with a cable tie. The strain relief prevents the wires from being torn out of the terminal if the cable is pulled.

Figure 11: Strain relief of the CAT cable

5) If the connected module is not the last module in the series, insert the further portion of CAT5 cable into the second terminal of the correct socket in the same way.
6) The last module does not require any termination or similar device.
7) Install the module in the mounting box. Follow the instructions under Fitting the modules (Page 38)

DETACHING INDIVIDUAL WIRES

Place a thin object (e.g. ballpoint pen) in the small pit in the middle of the orange lever to prevent slipping. Press on the orange part of the connector and the wire can be pulled out with a small amount of resistance.

Figure 12: Detaching the wires

Connecting REC OUT

The AUX / LINE OUT module must be installed one slot away from the MASTER CONTROL, as the two modules are connected to one another via a separate cable.

The connectors of this cable are mechanically coded and so cannot be connected the wrong way round. Use only the cable included with the REC module to connect this module.

Figure 13: Connecting RECORD to MASTER CONTROL

Connect the cable to the special connectors provided for that purpose (small white terminal strip).

Connecting XLR OUT PAS.

The passive line output module LINE OUT (PASSIVE) is connected to the MASTER CONTROL module. It can only be used once in the system.

The LINE OUT (PASSIVE) module takes the electrically balanced output signal and uses it to drive power amplifiers, mixing desks or similar equipment. The volume and tone are controlled by the MASTER CONTROL. The level also depends on the setting of the input module that is used.

Figure 14: Connecting XLR-OUT to MASTER CONTROL

The terminals of the LINE OUT module and the MASTER CONTROL module are coded so that the two channels, left and right, cannot be confused.

Connecting the power supply

ATTENTION

RISK OF INJURY!

The PSU 10 power supply unit must be connected last.

This module may only be installed by qualified technicians, observing relevant technical regulations and VDE directives.

Connection of the protective earth (PE) conductor is obligatory.

The power supply connector is mechanically coded and can only be connected to the socket of the MASTER CONTROL. Because of the cable, the power supply unit must be mounted directly adjacent to the MASTER CONTROL.

Figure 15: Connecting the power supply to MASTER CONTROL

Connecting TRAFO IN

The TRAFO IN plug-in module can only be used in conjunction with the AUX/LINE IN module.

You will need:

• TRAFO IN module and AUX/LINE IN module
• Supplied stainless steel cheese-head screw M3x5
• Size 2 Allen key

1) Undo the two screws on the underside of the AUX/LINE IN module. These screws fasten the black cover plate on the underside and the metal strain relief clip on the upper side.

Figure 16: Unscrewing the base plate

2) Remove the four blue jumpers from the top side of the circuit board and mount the transformer module in their place.

Figure 17: Removing jumpers

NOTE

Jumpers

After removing the jumpers, keep them in a safe place in case you want to remove the TRAFO IN module in the future. In that case, put the four blue jumpers back in their original position.

3) Fit the TRAFO IN module carefully.

Figure 18: Mounting the transformer

RISK OF DAMAGE!

When fitting the module, take care to ensure that none of the pins of the connector becomes bent.

4) Screw the transformer module in place with the screw supplied.
5) Attach the cover plate together with the strain relief clip.

Module wiring diagram

The wiring diagram provides information about the design and operating method of the individual modules of your AMM 10 multi-media connection system and shows how to wire them to one another correctly.

AMM 10 wiring diagram

This diagram illustrates one of the many ways of setting up a multi-media system in a room using the AMM 10. However, you can be as creative as you like in designing a multi-media connection tailored precisely to your needs.

NOTE

WIRING DIAGRAMS

The wiring diagrams can be found in the appendix at the end of the document.

4 Operation

MASTER CONTROL

The MASTER CONTROL module is connected to the PSU 10 power supply. It supplies power to the REC OUT recording output module.

The front panel of the MASTER CONTROL has volume, bass and treble controls. How you set these affects all output modules and the CONTROL OUT module, but not the REC OUT record module.

Maximum number within the AMM 10 system:

Only one MASTER CONTROL can be used. The system must include this module.

D-MIC IN

The front panel contains the volume control and the XLR input socket.

The "Mic / Line" slide switch is used to select an input sensitivity of -60dBu (Mic) or +/-0dBu (Line). Another slide switch is used to allocate the signal to the left (L) or right (R) stereo channel, or both channels simultaneously in mono operation (M).

Both slide switches are set back from the surface of the panel to protect against accidental switching. They can only be operated with a pointed object, such as a ballpoint pen.

Maximum number within the AMM 10 system:

Up to 10 MIC/LINE modules can be used, provided the power supply is adequate.

C-MIC IN

The preamplifier of the MIC/ZOOM module is equipped with a limiter and a configurable compressor. The limiter ensures a uniform maximum volume, while the compressor largely compensates for different mouth-to-mic distances or varying loudness of speech. The compressor function can be configured with jumpers prior to installation.

The front panel contains the volume control and the XLR input socket.

The "High / Low" slide switch is used to select an input sensitivity of -60dBu (High) or -40dBu (Low). Another slide switch is used to allocate the signal to the left (L) or right (R) stereo channel, or both channels simultaneously in mono operation (M).

Both slide switches are set back from the surface of the panel to protect against accidental switching. They can only be operated with a pointed object, such as a ballpoint pen.

Maximum number within the AMM 10 system:

Up to 10 MIC/ZOOM modules can be used, provided the power supply is adequate.

CD / PC IN

The AUX/LINE-IN module has two stereo phono sockets (L, R) and a 3.5mm stereo jack input. It also features a volume control.

Maximum number within the AMM 10 system:

Up to 10 AUX/LINE modules can be used, provided the power supply is adequate.

NOTE

EARTH LOOP

Connecting mains-powered audio sources with unbalanced outputs is often problematic, as an earth loop may be formed via the equipment's earth wire, antenna or similar.

If you want to use audio sources connected to earth, such as a PC, notebook, video recorder, tuner or similar with AUX/LINE-IN, we strongly recommend that you use the TRAFO IN (special accessory) (see "TRAFO IN" Page 54) plug-in module. This input transformer effectively breaks the earth loop.

MP3/PC IN

The front panel contains a volume control, a jack socket and a USB socket. This allows you to connect an MP3 player or Apple® iPod®.

Depending on its functionality, the connected device is supplied with battery-saving power, or the rechargeable battery is charged, via the USB socket. The audio signal from the playback device is fed into the 3.5mm stereo jack socket.

NOTE

USB SOCKET

The USB socket is used only to supply power, not to transfer data. The connected device must have an analogue audio output. Some devices, such as the Apple iPod Shuffle, cannot be charged simultaneously, i.e. during audio playback.

Maximum number within the AMM 10 system:

Up to 10 MP3 / USB POWER modules can be used, provided the power supply is adequate.

XLR OUT PAS.

The LINE OUT (PASSIVE) module is an output module with a stereo XLR output (Line Out).

The volume and tone are controlled by the MASTER CONTROL (Page 49). The level also depends on the setting of the input module that is used. If several LINE OUT (PASSIVE) modules are used in the system, the settings of the MASTER CONTROL affect all of them equally.

Maximum number within the AMM 10 system:

Up to 10 LINE OUT (PASSIVE) modules can be used, provided the power supply is adequate.

NOTE

EARTH LOOP

With long transmission distances, where conditions may be further complicated by nearby electromagnetic influences, electrically balanced inputs and outputs are pushed to their technical limits. Under these unfavourable conditions, or for receiving equipment with unknown input circuits, we recommend using the TRAFO OUT (special accessory) (see "TRAFO OUT" Page 55) plug-in module. The transformer in this module effectively breaks any earth loops and prevents asymmetries and transient currents.

XLR OUT ACT.

The LINE OUT (ACTIVE) module is an output module with a stereo XLR output (Line Out).

The volume and tone are controlled by the MASTER CONTROL (Page 49). The level also depends on the setting of the input module that is used. If several LINE OUT (ACTIVE) modules are used in the system, the settings of the MASTER CONTROL affect all of them equally.

Maximum number within the AMM 10 system:

Up to 10 LINE OUT (ACTIVE) modules can be used, provided the power supply is adequate.

NOTE

EARTH LOOP

With long transmission distances, where conditions may be further complicated by nearby electromagnetic influences, electrically balanced inputs and outputs are pushed to their technical limits. Under these unfavourable conditions, or for receiving equipment with unknown input circuits, we recommend using the TRAFO OUT (special accessory) (see "TRAFO OUT" Page 55) plug-in module. The transformer in this module effectively breaks any earth loops and prevents asymmetries and transient currents.

CONTROL OUT

The CONTROL OUT module is an output module with a headphone socket.

Use of this output module is especially recommended to help inexperienced operating personnel set levels. The result can be acoustically checked via the headphone output, unless the audio is played back in the same room anyway.

The front panel contains a volume control and a 6.3 mm headphone jack socket. In addition, 8 LEDs indicate the current signal level on both stereo channels.

Maximum number within the AMM 10 system:

Up to 10 CONTROL OUT modules can be used, provided the power supply is adequate.

REC OUT

The front panel of the AUX/LINE OUT output module has two stereo phono sockets (L, R) and a 3.5mm stereo output jack socket. The recording level can be set via the volume control. This is dependent on the input controls of the input modules, but independent of the master volume setting.

As a special feature, the AUX/LINE OUT module has a pre-attached connection cable which connects this module to the MASTER CONTROL. Therefore, AUX/LINE OUT cannot be more than one slot away from the MASTER CONTROL.

Maximum number within the AMM 10 system:

Only one AUX/LINE OUT module can be used.

NOTE

EARTH LOOP

Connecting mains-powered recording devices with unbalanced outputs is often problematic, as an earth loop may be formed via the equipment's earth wire, antenna or similar. If you want to use recording devices connected to earth, such as a PC, notebook or similar with the REC output module, we strongly recommend that you use the TRAFO OUT (special accessory) (see "TRAFO OUT" Page 55) plug-in module. This input transformer effectively breaks the earth loop.

PSU10

Power is supplied by the PSU 10 power supply unit. It is an efficient switched-mode power supply. Special design features guarantee optimum voltage smoothing and hence adulterated sound quality.

ATTENTION

RISK OF INJURY!

Other power supply units not approved by us are not to be used!

Depending on the composition of your system, the PSU 10 can supply at least 10 active modules.

NOTE

POWER SUPPLY

When planning your system, calculate the overall power consumption based on the technical data of the individual modules. If your system exceeds the capacity of the PSU 10, please contact us directly for a solution.

Maximum number within the AMM 10 system:

Only one PSU 10 module can be used. The system must include this module. If necessary, the PSU 10 can be replaced with a higher-capacity power supply unit.

TRAFO IN

The TRAFO IN plug-in module can only be used in conjunction with the AUX/LINE IN module. The unbalanced inputs are kept potential-free by the isolating transformers.

TRAFO OUT

The TRAFO OUT plug-in module can only be used in conjunction with the AUX/LINE OUT module or the LINE OUT (ACTIVE) module or the LINE OUT (PASSIVE) module. The outputs are kept potential-free and earth loops are effectively broken by the isolating transformers. Asymmetries and transient currents are also effectively prevented in this way.

5 Cleaning

Unplug the power supply unit from the socket.

Clean the surface of the unit with a moistened (not wet) cloth.

ATTENTION

Never use caustic or scouring cleaners or cleaning agents containing alcohol or solvents, since these may damage the enamel and plastic parts.
